LIlYE-SLUG-CASTING MACHINE.

Specification of Letters Patent.

Patented July 18, 192

Application filed September 4, 1820. Serial No. 498,298.

To allow/2.019s it may concern:

Be it known that l, SUNKER A. llisnr, a subject of the llingoi' GreatBritain, and a resident oi New York city, county and State oi"? NewYork, have invented certain new and useful Improvements inLinc-Slug-Casting Machines, of which the following is a specification.

My invention relates to the casting of line slugs and the object of theinvention is to enable a single mold type casting machine to be used forthe production of continuous unitary lengths ol typographical matter.

The invention involves a number of novel tleatures includingparticularly a special method of? permanently interlocking succeedingsections cast in the mold and the casting of the sections against acomposed matrix, which remains in engagement with and travels along withthe cast portion of the line slug.

These and other features or the invention will appear more fully as thespecific-atioii proceeds.

The invention is particularly adaptable to a type, lead and rule castingmachine like that disclosed in my companion application, Serial No.16%l,199, and for that reason I have disclosed the same as applied to amachine of that character, but- I wish it understood that the inventionis'by no means limited to that particular machine, and further, that thestructure maybe modified as regards the present disclosure withoutdeparture from the true spirit and scope of the invention.

In the accompanying drawing:

Figures 1 and 2 are vertical. sectional views taken through the moldchamber at the machine, Figure 1 being taken on sub stantially the planeof line 11 of Figure 2, and conversely, Figure 2, being taken onsubstantially the plane of line 2-2 of Fig ure 1.

Figure 3 is a transverse sectional view.

of dill ercntcross sectional forms which can he produced in the mold.

Figure 6 is a plan view, illustrating the permanent integration. of thecast sections.

Figure 7 is a detail sectional view, illustrating the additionalinterlock obtained where the cast sections overflow the matrices.

In the machine disclosed, the mold chamher, as indicated at 10 inFigureQ, is initiallv defined by upper and lower opposed horizontal moldblocks 11 and 12. and side walls formed by the vertical slides and Li.hen the first section is cast, the slide 13 which operates in the uppermold block is loweed to cooperate with the lower mold block 12, andafter this first section is cast, the slide is raised to the positionindicated and stands there until the casting or the slug is completed.

cast,

the slide Ll which operates in the lower meld block 12, is retracted topermit pusher l5 to enter the thus opened side of the mold chamber andto expel the casting therefrom. The mechanism by which these-slides arethus operated is not disclosed and may be similar to that shown in theapplication referred to.

The metal may he introduced into the mold chamber at the back through ajet opening as indicated at 16, to produce the castings 17.

The permanent interlock between the cast sections is accomplishedbynoviding the slide l l'with a vertical undercut rib 18 on the moldlace thereof, which iliorms an undcrcut channel or dove tail groove inthe adjacent side of the molded product, as indi clued at 19(seeparticularly Figure 4i).

The upper and lower mold blocks, as shown in vllligure 2. :lorm'ineffect a packing channel. at the left of the mold chamber receivin thecast product as it is advanced from the mold chamber. Alter the firstsection is cast, and the slide 18 iswithdrawn, the "front wallet themold is formed by the rear face of the casting just made and as thisisthe side which has the undercut groove in it the metal is flowed intothis undercut groove and the sections are thereby permanently andfixedly interlocl'zed.

In casting a typographical line slug, the matrices, which I have shownin detail at 20 in Figured, are composed in a holder or ,arrier 21 whichis then slidingly engaged in 'Aiter each section is a guide-way 22extending across the front of the mold chamber. 1 have illustrated thiscarrier in the form of an open frame, having ribs 23 at the upper andlower edges thereof engaging in the grooves 24-. provided at the top andbottom of the guide-way and have shown the matrices as held in. saidframe by being engaged over the ribs 25 which are interrupted at one endof the frame, asindieated at 26, to permit the matrices being slippedlate ally into the frame. The matrices when composed in the desiredorder and properly spaced, as by means of the blanks 27, may be held bya clamp screw .28 arranged to bear on the endmatrix.

As the casts are made, the metal congealing in the depressions of thematrices forms a temporary interlock between the cast portion of theslug and the matrix carrier, thereby causing the matrix carrier toadvance in step, and as a unit with the slug being cast. The matricesthus remain in contact with the casting during the entire operation,giving the metal ample time to set and enabling the work to proceedrapidly and smoothly. When the line is east, the slug may be separatedfrom the matrix, it being convenient for this purpose to entirely removethe matrix holder with the slug from the machine.

Means may be provided for stopping the machine or for giving a suitableindication when the slug is completed. Thus, I have indicated at 29 aswitch controlling a power or signal circuit 30 and having an arm 31standing in the path of travel of the matrix carrier and arranged to beoperated thereby when the slug casting is completed. This switchmechanism may be adjustable, as I have indicated, to enable the deviceto be set for line slugs of different length.

The invention is particularly suited to the casting of oversize typeface. This is accomplished by enlarging the mold cavity at the matrixend by means consisting in the illustration of opposed upper and lowergages 32 and 33, slidingly supported in the upper and lower mold blocksand adapted to be advanced or retracted by means of the thumb turns 3d,:35 which operate pinions 3G in engagement with racks 87 carried by suchslides. These gage slides are further shown as secured in their adjustedrelations by the set screws 38. i

In Figure 1, the lower gage slide 33 is indicated asretractedto' producean overhang at the lower face of the slug. In Figure .3, the lower gageis shown as projected into engagement with the upper gage so as to cutoff the forward end of the mold cavity and produce a shortened blankslug such as shown at the left in Figure 5. It will be evident that byretracting both slides, an overhang can be produced at both top andbottom of the slug, as shown at the right in Figure 5. This ability toenlarge the mold cavity at the matrix end maltes it possble to producevarious forms of display type and other large units with a mold of onlymoderate normal size.

hen casting with matrices which do not register laterally with the sidesof the mold chamber, as when the individual matrices are larger orsmaller than the mold chamber, the metal may flow laterally beyond thebounds of the mold chamber, producing an excess, as indicated at 39 inFigure 7 This is of advantage, however, in that the section next castwill interloclr with the more or less irregular shaped excess, andthereby produce a bond or interlock directly at the type face. This,with the undercut interlock in the body of the slug, produces a firm,strong slug.

The mold is preferably adjustable, as in my prior application, to enablethe casting of different body sizes and this, with the ads j ustabilityof the type face gages makes it possible to east typographical matter ina great many different sizes in a machine of only moderate size. It willbe clear that pictorial as well as strictly typographical matter may becast with this machine and I, therefore, wish it understood that theterm "typographical, and in fact, other expressions employed herein areused in a descriptive rather than in a limiting sense, except for suchlimitations as may be required by the prior art.

Ordinarily, the engagement of the cast portion of the slugwith thematrix will be sutlicient to provide a driving connection between thetwo, but in special cases, for instance, with electrotype or half-tonematrix blocks where the depressions are relatively shallow, a positivedrive for the matrix holder may be provided, as by equipping the ejectorwith a spring-pressed pawl 4.0 arranged to engage with properly spacednotches or teeth .41 on the matrix carrier. In the rearward stroke ofthe ejector this pawl will. simply slide over the toothed rib E23 on theupper edge of the matrix carrier, but on the forward stroke of theejector, the pawl will take hold of the carrier and insure its travelingalong in unison with the ejected portion of the slug.
